Quench and temper line-The two points you must consider
Our company has nearly 13 years of experience in the field of Quench and temper line, and Quench and temper line has been proven successful operation in user’s plant.The entire design and production will be completed in our factory. There is two points that must to be considered during bar induction heat treating :
1.Uniform heating: The angle between roller axis and torsion bars axis is 18 ~ 21 °. The torsion bars is rotating and go forward at the uniform rate for uniform heating. Rollers between furnace are 304 non-magnetic stainless steel and water-cooled.
2.Uniform cooling:To meet the requirements of different hardenability, spraying system adopts multi-level spray cooling and the pressure & flow in water spray ring at all levels is adjustable.The torsion bars will be placed in the middle of spray ring to ensure uniform pressure and flow.
So the bars needn’t straightening after heat treatment with our quench and temper line The surface hardness difference is very small.
